Review on Intake Exhaust TRX400EX TRX400X 1999 2014 by Reid Longtin

Upgrading to the Intake Exhaust for my TRX400EX has been a game changer .My analysis of THIS product showed that there was an increase in horsepower and acceleration. The sound is perfect, not too loud and not too quiet. Installation was easy and straightforward. I'm very happy with this purchase and would recommend it to anyone looking to improve their automotive performance. The only downside was that it was a bit pricey compared to other options..
